The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. libgaiagraphics-0.5/headers/0000775000175000017500000000000012110373524013103 500000000000000libgaiagraphics-0.5/headers/Makefile.am0000664000175000017500000000011712110373454015060 00000000000000 noinst_HEADERS = gaiagraphics_internals.h include_HEADERS = gaiagraphics.h libgaiagraphics-0.5/headers/gaiagraphics_internals.h0000664000175000017500000012012212110373454017675 00000000000000/* / GGRAPH_internals.h / / internal declarations / / version 1.0, 2010 July 20 / / Author: Sandro Furieri a.furieri@lqt.it / / Copyright (C) 2010 Alessandro Furieri / / This program is free software: you can redistribute it and/or modify / it under the terms of the GNU Lesser General Public License as published by / the Free Software Foundation, either version 3 of the License, or / (at your option) any later version. / / This program is distributed in the hope that it will be useful, / but WITHOUT ANY WARRANTY; without even the implied warranty of / MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. libgaiagraphics-0.5/src/0000775000175000017500000000000012110373524012257 500000000000000libgaiagraphics-0.5/src/gaiagraphics_tiff.c0000664000175000017500000031060512110373454016004 00000000000000/* / gaiagraphics_tiff.c / / TIFF auxiliary helpers / / version 1.0, 2010 July 20 / / Author: Sandro Furieri a.furieri@lqt.it / / Copyright (C) 2010 Alessandro Furieri / / This program is free software: you can redistribute it and/or modify / it under the terms of the GNU Lesser General Public License as published by / the Free Software Foundation, either version 3 of the License, or / (at your option) any later version. / / This program is distributed in the hope that it will be useful, / but WITHOUT ANY WARRANTY; without even the implied warranty of / MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

All colors within a * histogram cell will be mapped to the same colormap entry, namely the one * closest to the cell's center. This may not be quite the closest entry to * the actual input color, but it's almost as good. A zero in the cache * indicates we haven't found the nearest color for that cell yet; the array * is cleared to zeroes before starting the mapping pass. When we find the * nearest color for a cell, its colormap index plus one is recorded in the * cache for future use. The pass2 scanning routines call fill_inverse_cmap * when they need to use an unfilled entry in the cache. * * Our method of efficiently finding nearest colors is based on the "locally * sorted search" idea described by Heckbert and on the incremental distance * calculation described by Spencer W. Thomas in chapter III.1 of Graphics * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that * the distances from a given colormap entry to each cell of the histogram can * be computed quickly using an incremental method: the differences between * distances to adjacent cells themselves differ by a constant. This allows a * fairly fast implementation of the "brute force" approach of computing the * distance from every colormap entry to every histogram cell. Unfortunately, * it needs a work array to hold the best-distance-so-far for each histogram * cell (because the inner loop has to be over cells, not colormap entries). * The work array elements have to be ints, so the work array would need * 256Kb at our recommended precision. This is not feasible in DOS machines. [ 256*1024/4 = 65,536 ] * To get around these problems, we apply Thomas' method to compute the * nearest colors for only the cells within a small subbox of the histogram. * The work array need be only as big as the subbox, so the memory usage * problem is solved. Furthermore, we need not fill subboxes that are never * referenced in pass2; many images use only part of the color gamut, so a * fair amount of work is saved. An additional advantage of this * approach is that we can apply Heckbert's locality criterion to quickly * eliminate colormap entries that are far away from the subbox; typically * three-fourths of the colormap entries are rejected by Heckbert's criterion, * and we need not compute their distances to individual cells in the subbox. * The speed of this approach is heavily influenced by the subbox size: too * small means too much overhead, too big loses because Heckbert's criterion * can't eliminate as many colormap entries. Empirically the best subbox * size seems to be about 1/512th of the histogram (1/8th in each direction). * * Thomas' article also describes a refined method which is asymptotically * faster than the brute-force method, but it is also far more complex and * cannot efficiently be applied to small subboxes. It is therefore not * useful for programs intended to be portable to DOS machines. On machines * with plenty of memory, filling the whole histogram in one shot with Thomas' * refined method might be faster than the present code --- but then again, * it might not be any faster, and it's certainly more complicated. */ /* log2(histogram cells in update box) for each axis; this can be adjusted */ #define BOX_R_LOG (PRECISION_R-3) #define BOX_G_LOG (PRECISION_G-3) #define BOX_B_LOG (PRECISION_B-3) #define BOX_R_ELEMS (1<actual_number_of_colors; int maxR, maxG, maxB; int centerR, centerG, centerB; int i, x, ncolors; int minmaxdist, min_dist = 0, max_dist, tdist; int mindist[MAXNUMCOLORS]; /* min distance to colormap entry i */ int pixel; int r; int g; int b; /* Compute TRUE coordinates of update box's upper corner and center. * Actually we compute the coordinates of the center of the upper-corner * histogram cell, which are the upper bounds of the volume we care about. * Note that since ">>" rounds down, the "center" values may be closer to * min than to max; hence comparisons to them must be "<=", not "<". */ maxR = minR + ((1 << BOX_R_SHIFT) - (1 << R_SHIFT)); centerR = (minR + maxR) >> 1; maxG = minG + ((1 << BOX_G_SHIFT) - (1 << G_SHIFT)); centerG = (minG + maxG) >> 1; maxB = minB + ((1 << BOX_B_SHIFT) - (1 << B_SHIFT)); centerB = (minB + maxB) >> 1; /* For each color in colormap, find: * 1. its minimum squared-distance to any point in the update box * (zero if color is within update box); * 2. its maximum squared-distance to any point in the update box. * Both of these can be found by considering only the corners of the box. * We save the minimum distance for each color in mindist[]; * only the smallest maximum distance is of interest. */ minmaxdist = 0x7FFFFFFFL; for (i = 0; i < numcolors; i++) { /* We compute the squared-R-distance term, then add in the other two. */ pixel = quantobj->cmap[i]; r = color_get_red (pixel); g = color_get_green (pixel); b = color_get_blue (pixel); x = r; if (x < minR) { tdist = (x - minR) R_SCALE; min_dist = tdist * tdist; tdist = (x - maxR) R_SCALE; max_dist = tdist * tdist; } else if (x > maxR) { tdist = (x - maxR) R_SCALE; min_dist = tdist * tdist; tdist = (x - minR) R_SCALE; max_dist = tdist * tdist; } else { /* within cell range so no contribution to min_dist */ min_dist = 0; if (x <= centerR) { tdist = (x - maxR) R_SCALE; max_dist = tdist * tdist; } else { tdist = (x - minR) R_SCALE; max_dist = tdist * tdist; } } x = g; if (x < minG) { tdist = (x - minG) G_SCALE; min_dist += tdist * tdist; tdist = (x - maxG) G_SCALE; max_dist += tdist * tdist; } else if (x > maxG) { tdist = (x - maxG) G_SCALE; min_dist += tdist * tdist; tdist = (x - minG) G_SCALE; max_dist += tdist * tdist; } else { /* within cell range so no contribution to min_dist */ if (x <= centerG) { tdist = (x - maxG) G_SCALE; max_dist += tdist * tdist; } else { tdist = (x - minG) G_SCALE; max_dist += tdist * tdist; } } x = b; if (x < minB) { tdist = (x - minB) B_SCALE; min_dist += tdist * tdist; tdist = (x - maxB) B_SCALE; max_dist += tdist * tdist; } else if (x > maxB) { tdist = (x - maxB) B_SCALE; min_dist += tdist * tdist; tdist = (x - minB) B_SCALE; max_dist += tdist * tdist; } else { /* within cell range so no contribution to min_dist */ if (x <= centerB) { tdist = (x - maxB) B_SCALE; max_dist += tdist * tdist; } else { tdist = (x - minB) B_SCALE; max_dist += tdist * tdist; } } mindist[i] = min_dist; /* save away the results */ if (max_dist < minmaxdist) minmaxdist = max_dist; } /* Now we know that no cell in the update box is more than minmaxdist * away from some colormap entry.
